Your demo is playable on desktop too with only a few glitches, & I think it's going to make a great mobile game. I was compelled enough to play through all the levels which were well-designed & ramp up in difficulty nicely. Some ideas:
- The immovable metal crates could be more visually distinct from the wooden moveable crates. Maybe make them look more like parts of the scenery, like girders or rock, & less like crates.
- Are you going to add a destruction effect when you click on something? That would make clicking much more satisfying & fit with the mining theme.
- As an extra mechanic, how about explosive crates that explode if you destroy an adjacent object? I know you've already got the skulls as things to avoid, but some TNT crates could also play a role in solving the levels (by moving things from their physics impulse) as well as being obstacles.
hehe its nice that you like the game! thanks a lot, and for your questions:
1 - its a pretty interesting idea but for the moment im going to keep it like crates because thats remember me the firts dlifo version and thats a nostalgic stuff
2- YES! and sounds, but for the moment i dont have any musician.
3 - there was a TNT before in the development but due to level design reasons is not inside the main game, but its already in the code. if i find a way to put the TNT back i will put it.
here is a very old version of the game:
